Six-Gun is a fictional Decepticon weapons platform and fortress defense robot in the Transformers franchise, best known as a powerful base-form ally of Metroplex in the Transformers: Generation 1 continuity. He is typically portrayed as a combiner component or city-bot support unit, specializing in heavy artillery and defense. Rather than a traditional individual character with a personal name structure, Six-Gun is usually treated as a single moniker. He serves as a guardian and fire-support specialist, helping defend Autobot strongholds against enemy attacks.
